# How to calculate the area of the room – the formulas and methods of calculation

Sharing is caring!

When you start repairing, you must purchase a sufficient amount of wallpaper, glue, paint, and other materials. To do this, you need to know how to calculate the area of ​​the room. If you understand how to get and apply the necessary measurements, then in the future, for example, when buying or selling real estate, you will be able to independently calculate the floor space and check the documents. The remodel measure guide helps you the best there.

Simple rectangular or square room

To find out how to calculate the floor area of ​​a room, you must determine its shape. In the room, which is a rectangle or square, you need to measure the length and width and multiply the values ​​between themselves. You will get the area of ​​the room in square meters.

The formula by which you can calculate the area:

S rooms = A x B, where A is the length, B is the width.

For the measurement, you can take the usual tape measure. To get the most accurate result, it is recommended to measure the length at the beginning of the wall and the end and, if the numbers differ, take the arithmetic average.

Room with niches or overhangs If the room has niches, protrusions, plumbing, or ventilation structures, then it is necessary to measure the area of ​​each section separately. If it is a niche in the wall, then the area of ​​the room must be added to the area of ​​the recess. If this is a projection, then, accordingly, its area will need to be subtracted from the area of ​​the room.

The same principle should be followed if you want to know how to calculate the ceiling area of ​​a room. An even, rectangular ceiling without any niches and protrusions means that it must be measured in length and width, and then count the area by simple multiplication. If you plan to insulate the floor using heating elements, then you will need to subtract the area occupied by heavy furniture from the total floor area.

Complex room

Often there are rooms of unusual shape. If there is a possibility, then you need to divide the room into several rectangles, calculate the area of ​​each and fold.

Features of calculating the area of ​​simple walls and walls containing protrusions and niches

Now let’s consider such an important point as the calculation of the area of ​​the walls of the room. Knowing this value, you can buy the right amount of wallpaper for repair. Of course, you can contact a consultant in a hardware store, and he will tell you how to calculate the area of ​​the walls. There is nothing difficult in this: measure the length, width, and height of the room. To obtain more accurate results, it is necessary to subtract the area of ​​door and window openings from the total area of ​​the walls.

The area of ​​the walls of the room with projections or depressions will differ from the area of ​​the walls of a simple room. Do not forget to add to the main value the area of ​​the wall of the protruding or in-depth area. Be careful when making measurements and calculations. If you are using a laser tape measure, then make sure that the beam is directed strictly perpendicular to the wall. Otherwise, you will get a big error in the results.
